'l ll 10 'for cleaning it without dismantling the parts. As shown in Fig. 2 the compartment 1 isprovided at its lower end with an opening closed by a hinged cover 14. This enables meto readily remove the heavy particles of dirt which fall to the bottom of the compartment. l have shown in Fig. 2 the iloo'r 27 having an opening over the sieve 10 and closed by a cover 15. By this means a brush may be inserted teclean the sieve. lllhen, however, it is desirable to remove the sieve the bolts passed through flanges 11 may be removed and pipe 5 unconpled. This allows of casing 13 being removed trom casing 7 and releases the sieve. Access to the interior of casing 7 may be had through a hand hole closed by a cover 16.

17 is the water supply pipe and 24 indicates the normal level of the water in the liquid separator 2.

18 is the liquid separator drain.

19 shows a drain from the dry separator which may be used when scrubbing water is collected by the apparatus.

.20 is a gage glass which shows the height of the water in the4 lliquid' chamber, 25 representing a clean out plug.

21 is a check valve which connects the dry and liquid compartments and thereby provides for equal pressures in the two chambers. (See Fig. 6.) Y A 22 is a cylindrical shell or guide for the air stream enteringcompartment l. .Being centrally located thiscylinder permits the air to whirl about it without obstructing the current. As the air has to descend a snort distance beforev enteringv this cylinder the heavier particles will. fall to floor 2.

23 is the internal end of elbow Ll.

The locations of elbows 3 and 1, are such that connections are easily and quickly made to suitable piping supplying impurities-laden air from the cleaner', and carrying illtered air to the suction means. The arrangement of the vertical air ent-rance G, baille plate 8, perforated plate 10 and baille floor 27, provides effective means for arresting the impurities particles and se arating them iis-m the ilowing air. .As t ie air passes through the sieve l() and leavestthe liquid, it encounters the iloor 27 of the dry compartment in its travel to outlet fl. This flooring thus acts as a baille and tends to further iree the air ot dust particles. The check valve 2i insures equality of pressures in compartment l and the space between the latter and casing 18.

lu operation, the suction means is started and the cleaner tool is applied, the impurities-laden air being conveyed to chamber 1 thi-nigh the inlet 3 by suitable hose and piping. The air passes to the annular space between. the walls of the cylinder 22 and those of :oihpartiiient l.' A circulary motion ensues and the air, moving at a comparatively slow velocity, frees itself of the heavier particles which i'all by gravity to the iloor 27 of compartment 1. The streams are then directed through the central cylinder 22 and out ot the dry separating compartment at After passing through pipe 53L the air stream enters the liquid compartment 2 through pipe (3 in a vertical direction. Thisdircction of the stream is deflected by the baille plate 8, thereby allowing'the water to partially wash the air stream. The air currents then pass around the edges of baille plate 8 bein" thus divided and distributed, and througi the finely perforated plate 10, where the impurities carrying air bubbles which have passed through the water are disintegrated,

and the dirt taken up by the water. The air streams now passing through thevplate 10 and toward the outlet 4, are deflected again in their paths by the iloor 27 of compartment l, which acts as a baille plate giving the air a tortuous passa e. The `air then `Apasses through the annu ar space between the cylindrical walls 1 and 13, and out through outlet 4 to thc suction producing means.

Practice has demonstrated the necessity `for readily gaining access to thev interior 'of vthe separators for the purpose of cleaning the parts, especially the perforated plates. It has also shown thatgunlcss means e employed for distributing the current of dust laden air the vseparating elements will become clogged owing to the quantity of dirt which a single jet of air will cause to gather at one oint.v Furthermore, while the dust laden air should be given a whirlingaction and downward. direction in the dry separator, yet the outlet therefrom 'should be away fromthiscircular path to avoid the air being drawn directly into it without losing any of the dirt particles cntrained with it. It will be obvious to those 'skilled in the art that by my invention these essentials are fullyprovided for.

l claim as my invention 1. ln a separator for suction eleaiiing apparatus, a two part casing, means for coupiiig said parts, said casing comprising a dry cmnpartment and a liquid compartment, a pipe leading from said dry conipurtiiieiit-to said liquid compartment and terminating beneath the liquid level thereof, and a pei'- forated plate above the extremity of said pipe, said plate being secured by saidl coupling means.

2. ln a separator t'or suetioq cleaning apparatus, a casing con'iprising two compartments, oiica dry separator and the other a circuinposed liquid separator, an annular spa-re being formed between said"coinpart ments, a pipe connecting said separators and terminating below the Iliquid, tie travel ot the dust-ladcn air beingtroni said dry separator to said liquid separator, a solid baille till] oeaeei plate extending over and around-the outlet from said pipe, a perforated plate in rear of said baille plate below the liquid level and an outlet pipe leading 'from the space. between said compartments. i

3 ln a separator for suction cleaning ap paratus, a casing adapted to contain water V to constitute a liquid separator, a dry separator within said casing above the water level, an annular space open to' the water be ing provided between the walls of said dry separator and said casingan outlet ipe leading from said space, a pipe leading rom said dry separator to said liquid separator andV terminating belowI the surface of the liquid therein7 and a perforated plate secured to said casing and in'nnersed in the liquid above the termination of said pipe and extending entirely across said casing.

Ll. ln a separator orsuction cleaning apparatus, a two part casing comprising a dry separatorai'id a subjacent liquid separator, means for coupling said casing parts, means for conducting air from said dry separator to said liquid separator and discharging it beneath. the liquid level therein, a perforated plate arranged transversely of the path of the air discharging into said liquid separator, means for supporting saidplate, and ribs or braces secured to said dry separator and to said plate. 1

5. In a separator for suction cleaning apy paratus, the combination with the twopart casing and means for coupling said parts,

said casing containin a dry separator having a cylindrical outet depending from its to and means for introducing air between said cylindrical outlet and the Wall of the separator, of a liquid se arator formed by said casing beneath sai Vdry separator, a pipe leading :trom said dry separator into said liquid seg'iarator and havin a vertical extremity discharging below the gliquidlevel., a solid balile plate supported by the Walls of the casing and disposed across and above the outlet from said pipe, a perforated plate dis posed transversely of the liquid compartment abve said baille plate and having its ends supported by said coupling means, and an outlet from said liquid separator.

6. In a separator for suction cleaning apparatus, the combination with the liquid compartment having a solid conical spreader transversely arranged therein, an airpipe having a vertical outlet discharging below the center of said spreader, and a perforated plate above said spreader, ot' a dry compartment above the liquid compartment, the Hoor of said dry compartment extending across said plate to act as a baille and a tubular connection between said compartments. In testimony whereof, l have signed this specification in the presence of two subscribing witnesses.
